Initial Inspection and Diagnostic Overview

Inspection And Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical and electrical damage.

3. If inspection reveals an obvious concern that is readily repaired, correct the concern before continuing with Inspection and Verification.
4. If the concern remains after inspection, connect the scan tool to the Data Link Connector (DLC) located beneath the instrument panel to perform DATA LINK DIAGNOSTICS (DTC) test. If the scan tool responds with NO RESPONSE/NOT EQUIPPED for the Lighting Control Module (LCM), go to Pinpoint Test A. If the DATA LINK DIAGNOSTICS test is passed for the LCM, retrieve continuous DTCs and execute self-test diagnostics for the LCM to retrieve current DTCs.
5. If the self-test is passed and no DTCs are retrieved, go to the Symptom Chart to continue diagnostics.
6. If DTCs are retrieved, go to the Lighting Control Module (LCM) Diagnostic Trouble Code (DTC) Index to continue diagnostics.
7. If the LCM cannot be accessed by the scan tool, go to Pinpoint Test A.
